I'm having trouble understanding this sentence by Noam Chomsky. Noam published many English-related scientific papers in his professional career and I have no doubt that this italicization is purposeful. It seems like he is setting up a contrast, but then the italicization wouldn't be on the word "their." Here's the sentence and its context:
Legitimizing versus Meaningless Third World Elections
“Third world elections provide an excellent testing ground for a propaganda model. Some elections are held in friendly client states to legitimize their rulers and regimes, whereas others are held in disfavored or enemy countries to legitimize their political systems. This natural dichotomization is strengthened by the fact that elections in the friendly client states are often held under U.S. sponsorship and with extensive U.S. management and public-relations support.”

Note that this is the first paragraph in the chapter, with the chapter title emboldened. Thanks for your help!
